The FCC Wants You to Know
This equipment has been tested and found to comply
with the limits for a Class B digital device, pursuant
to Part 15 of the FCC Rules. These limits are designed
to provide reasonable protection against harmful
interference in a residential installation. This equipment
generates, uses and can radiate radio frequency energy
and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio
communications.
However, there is no guarantee that interference will
not occur in a particular installation. If this equipment
does cause harmful interference to radio or television
reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following
measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and
receiver.
• Connect the equipment into an outlet on a circuit
different from that to which the receiver is connected.
• Consult your local RadioShack store or an
experienced radio/TV technician for help.
If you cannot eliminate the interference, the FCC
requires that you stop using your clock.
Changes or modifications not expressly approved by
RadioShack may cause interference and void the user’s
authority to operate the equipment.

Q - How far into Eastern Europe is the Continental
Europe atomic clock signal detected?
A - The atomic clock at Mainflingen transmits
within an area of about 1500km radius. The
coverage area varies with weather conditions
and time of day (coverage increases up to
2500km radius at night).
Q - Is signal detection affected by physical
barriers?
A - Not usually. Long wave frequency is used for
atomic clock signal transmission, which is less
affected by physical barriers. Major barriers,
such as steel reinforced concrete, may cause
interference.
Q - How long do the batteries last?
A - Battery life depends on how often the backlight
is used, since the backlight draws a lot of
power. If the backlight is used once a day, the
batteries will last approximately 9-12 months.
Q - If you are in an area covered by two atomic
clock signals, such as Western Europe, which
signal will be received?
A - The first signal the clock receives will be used
to set the time. If this does not correspond
to your current location, you can select your
current city so the time is adjusted relative to
GMT.
